Abstract

The business expansion of sugarcane can be done using marginal land, such as wet land. This study attempted to get the right doses of ZA fertilizer applied to several sugarcane cultivars, which are tolerant to flooding in two different locations. The research was carried out in Jubung Agrotechnopark garden,  University of Jember and seed gardens of Dewisri Bondowoso, from November 2015 to November 2016. The experiment was arranged in factorial randomized complete block design. The first factor was the doses of ZA fertilizer, consisting of 3 levels of treatment, i.e. 0 kg.ha-1 (without ZA fertilizer), 500 kg.ha-1 and 1000 kg.ha-1. The second factor was 4 sugarcane cultivars,  consisting of flood-tolerant sugarcane cultivars from 2014 screening result, i.e. PSJT 941, Bulu Lawang, PS 865 and Kidang Kencana. The results showed that the application of ZA fertilizer at 1000 kg.ha-1 affected the height of stems, the number of tillers, diameter of the stem and the number of segments. Meanwhile, the application of ZA fertilizer at 500 kg.ha-1 affected the number of leaves, fresh weight of shoots, dry weight of shoots, fresh weight of roots, dry weight of roots, brix content, and the content of sucrose and reducing sugar. Flood-tolerant sugarcane cultivars are shown by the highest brix and sucrose fertilizer, observed in  PS 865, Bulu Lawang, PSJT 941, and Kidang Kencana, sequentially. The highest content of reducing sugar was found in PSJT 941, PS 865, Kidang Kencana, and Bulu Lawang, successively.

Abstract

Indicator of coffee resistance to leaf rust attack (Hemileia vastatrix) is needed to select superior coffee plants resistant to biotic stress. This study aims to find the relationship between the content of secondary metabolites and the intensity of leaf rust attack, so that it becomes a reference in the selection of future coffee plants. The experimental design used was a completely randomized design (CRD) with several coffee clones as a treatment. This test tested 5 Arabica coffee clones consisting of Komasti, Maragogik, Usda, Andong sari, and HDT clones. Each consists of 3 replications, and each replication consists of 2 sample plants. Observations were made by observing the intensity of the attack, and plant metabolites such as phenolic content, flavonoids and antioxidant activity were observed when the leaves had been attacked by Hemileia vastatrix. Correlation of leaf rust attack levels with phenolic content, flavonoids and antioxidant activity showed a relationship between each observation variable. Flavonoid content in certain conditions can be used as an indicator to get Arabica coffee plants that are resistant to the attack of leaf rust.

Abstract

A prolonged dry season can cause drought stress and have an unfavorable impact on the growth of tomato plants, resulting in crop failure. Therefore, research is needed on the resistance of tomato varieties to drought stress. The recommended technique for drought resistance screening in tomatoes is in vitro cultivation using Polyethylene Glycol (PEG). The research aimed to obtain new varieties that could be used as promising lines for varieties tolerant to drought stress. The research method used included using ingredients in the form of 5 varieties of tomatoes (Ratna, Intan, Chung, Palupi, and Amelia) and 5 concentrations of PEG chemicals (0%, 5%, 10%, 15%, and 20%). Each seed of each tomato variety that had been sterilized using hypochlorite was germinated on MS0 media, then the germinated seeds with a size of ± 0.3 cm were transferred to MS0 + PEG treatment medium with each treatment concentration. The seeds that had been planted on the PEG-treated medium were then observed for growth for ± 4 weeks. The research data were analyzed using analysis of variance (ANOVA) and followed with DMRT at the 5% significance level. Based on the results, Palupi variety is the most tolerant variety, and Ratna variety is the most intolerant variety to drought stress. The higher the concentration of PEG used, the more it inhibits plant height, root length, and fresh weight of the roots.
